COMBINATIN PIN AND `'IUIWBLIEIJR LOCK.

Application filed-Getober 28, 1925. Serial No. 65,296.

This invention relates to locks in general, and particularly to padlocks, the` bodyof which is made of one solid block of metal.

The main object of my invention `isto provide a lock of the above character which will operate with a combination of locking pins and circular tumbler` disks, and `which will permit a `great variety of combinations with very simple means. i

Another object of my invention is to provide a lock of the above description which will be exceptionally strong and durable in constructiom'and which will show` agreat `resistance to unauthorized opening or burglarizing ofthe same. I

Still other objects of my invention are: to provide a lock which will be simple in construction and operation, inexpensive, adapted to mass manufacturing, and adapted to be opened by a simple key of special construction. y

Further objects and advantages of the invention will be evident from the description of the same, to follow hereinafter.

` The invention also resides incertain novel features of construction and organization, which will be fully setforth-hereinafter' and pointed out in the claims. i 1 Reference is to be had tothe accompanying drawings, `which illustrate as an example the preferred embodiment of my invention, in which drawings 'like characters of reference indicate like parts in the several views, and in which :f- :z5 Fig. l is a sectionalview of my assembled lock, together 4with its key, certain portions having been removed, the section being taken Fig. 2 `s a horizontal sectional viewof my v lock fully assembled, the section beingtaken l on` the line 2-'-2 of Fig. 1,-but with certain partsomitted. A y

\ Fig. 3 is aside elevation "of the lock, thekey having been removed therefrom; y y

r v Fig. l is a front elevation of a key of particular construction to be used in connection with my padlock, while Fig. 5 is a topview of said key." e Referring now to the drawing with characters of reference, 10 indicates the main body of my lock, heilig in the form of a rectangu- .lar block of metal, preferably of brass, so as to make my lock more resisting to the injurious effects of the weather and to rust.` In the block of metal 10, Illirstprovide a bore 11 of comparatively large diameter to receive the extreme end of the leg12 of shackle 13 and the cylinder of the locking and opening elements combined therewith. The bore 11 stops short ofthe opposite end 14 of the metal 60 block 10, as at 15, and is continued in a concentric through bore 16, of considerably smaller diameter, so as to provide `a sliding fit for the leg 12 of the shackle. 1 i

Acollar17is provided on said leg, limit- 65 mg its downward movement. but mainly for the purpose of protecting the bores 11 and 16, and the elements contained .y therein, from water and other atmospheric influences. The lower end of the leg 12 is provided with a plu- 70 rality of recessed portions 18, leaving collars 19 therebetween. y Each ofsaid collars is providedwith two opposingly set slots 20 in them, the slots V2O being cut in axial registering relations. The bottom end of the lock is provided with La `disk 21, secured thereto by any suitable means, as bya flat headed seti` u screw, disk 21 normally restingon a cup like plug 22 of the same material as block 10, said plug being secured in the bore 11 with its out- 80 side surface flush withthe corresponding surface ofthe block 10 and being `finished in a u similar manner `so as to make it practically impossible to, distinguish the plug from the rest` ofthe block. The' restofthe bore 11, 85

.above .the cup shaped plug 22, is filled witha plurality of alternately set tumbler disks 23 and spacing washers 24C. the thickness of the tumblerdisks corresponding to the height of the recesses lSgand the thickness of the spacing washers 24 being equal to that of collars `19, and said tumblers, and spacing washers u being placed in an exact registering relation with said recesses and said collars, respectively. Each of the tumbler disks 23 and the 95 spacing washers 2 4z`are also provided with central openings or holes 25.y of substantially i equal diameters, and,` of such `dimension that said holes shouldpermit an` easy movement of y the leg 12 of the shackle -with its collarsin 100 them. Thetumbler disks 23, however, are also provided with two inwardly projecting lugs or noses 26^which` will normally be turned underneath Vthe intact portions of collars 19, thereby lockingthe leg 12, but which.

whenplaced in registering relation `with the slots 20. will be adapted to` pass through said slots and thereby permit a sliding movement of the lower end ofthe leg 12. l

. `A helical spring 27 is placedbetweenthe 110 disk `21 and the` lowest spacing washer, tending to pull the leg 12 downwards when its sliding movementvr is permitted into a position where tuinblers 23 may be turned into their locking position under the influence of means to be described presently. The block has al plurality of further bores of smaller diameter, set in two rows, 28 and 29, trans* versely to the bore 11. A pin 30 is placed in each bore 28, being urged into bore 11 by a spring 31 resting on a lirmly litting plug 32. Tumbler disks 23 have arcuate recessed portions '33,- on which the pointed ends 34 o the pins 30 may play and said tumbler disks will normally be turned to the locking positions' described above, andliinited by the pins 3,4V in bores 29, at Vthe saine time pins 32H are the elements to be used to set the tumbler disks into the opening positions de scribed hereinbefore. Said pins are slidable i'n bores' 29 and across pin 35 serves to limit their playin both directions'by playing in the slots 3G insaid pins. ASlots 36 in said v'pins are in such positions and of such length in pins 311" that when said pins are pushed in an 'outward direction to the fullest liinit until the inward ends 37 of the slots 36 will hit the cross pin 35, noses or lugs 26 turned into locking positions `as shown vvin' Figure Y v 0 In order' to open the lock, the tumblers 3 23 must be turned in such 'a position that 'their lugs 26 should register `with the slots 20in ycollars 19. The keyshown iny Figures vr1',"`PA1-fand"5 'is used 'for this purpose, 'said key consisting `oi an angular piece v38 With the Vtwosides`-39- and 40, of which 39 is a key 5 proper-with the pins 41 set therein to 'operate vthev pins 34, While `the side 40fhas fa trans- Versely set single pin 42 adapted'ft'o engage finlthef'hole 43 ofthel rblock 1'() to'pivotally 4,0v fs-jupp'ort the key and to permit the operator to press it down so that the pins L11 will `enterfbores29 and ush'the pins 34 inward "ly, The pins 41 of the key 39 are nifad'e et Vldilierent heightsin such a manner that when the key'i's fu-lily presseddown on 'the surface '1t)"-`bloek10,pins 34 will turn their re- 'spectivefttiniblers 23 into registering positions btween'f all the lugs 26 and slots 20. lInsn'ch"jgifositions of the tumbler-s, the pins 30"'will` be Ipressed (intw-ardly, against the springs '31,and the lock is 'in an open positionso thatl'eg 12 of the shackle can bep'nlled 1' upw'a-rdly--agains'tthe action of spring 27 and `L`-tlie termination Pl of its other leg 45 lifted out of'ttherecessd, provided for the same "'in'fk'oloeky "-1@ and tliepadlockopene'd inthe i usual.

IIole Ai7 in the ,key 38 can be used to attach the key to a key holder.

Various changes inthe torni, proportions, and minor details ot my invention may be lresorted to at will without departing from the spirit and scope thereof'. lIenee I coi1- sider myself entitled to all such variations as may lie within the tei'ins of iny claims.
